EDWARD A. JARVIS, OF WEST NEW BRIGHTON, NEW YORK.

PARKING-LAMP.

To all whom it may concern i Be it known that I, Enwann A. Janvls. acitizen of the United States, residing at 'lVest New Brighton, county ofRichmond,

State of New York, have invented certain new and useful Improvements inParking- Lamps, of which the following is a full, clear and exactdescnption.

This invention relates to improvements in parking lamps for automobiles;in other words. lamps used while'automobiles are i parked in lieu of thehead and tail lights, thereby savmg considerable battery energy.

- "'Qne of the objects of my invention is to produce a combined electricparking lamp,

[that is to say, a lamp showing red from the rear and white from thefront, and a movable mirror, the mirror to be used for dayred lens 11.

light driving to observe those behind, to

'gether with means to complete theci'rcult for a bulb, within the lamp,when the mirror is moved out of alinement with the lam when the lamp isto be used. Referring to the accompanying drawmg:

Figure 1 illustrates a vertical sectional view of a lamp embodying myimprove-- ments;

Fig. 2 is an enlarged sectional view, the section being taken on a line2--2 in Fig. 1;

Fig. 3 is a fragmentary vertical sectional view, the section being takenon a line 33 in Fig. 2;

Fig. 4 is a sectional view, the sectionbeing taken on a line 4-4 in Fig.1;

Fig. 5 is a fragmentary vertical sectional view, the section being takenon a line 5-5 in Fig. 1;

Fig. 6 is a sectional plan view, the section being taken on a line 6-6in Fig. 5; and

Fig 7 is a modified form of the switch portion of my invention.

As herein embodied. the lamp consists of a base 8 carrying a splitexpansible shell 9 to hold a front white lens It) and a rear The lenses10 and 11' are held in annular channels 12 in said shell. The shell 2')at one end is rigidly secured to the base by a rivet 13 (in thisinstance), the other end being slotted as at l4 to straddle a clampingbolt 15, which passes loosely Specification of Letters Patent.

secured in clamped position by tightening the bolt 15. To remove thelenses, bolt 15 will be loosened and the shell spread open suflicientlyto allow the lenses to be taken out. Theslot 14 permits the shell'to bespread. As can be seen. the base 8 is hollow and at its upper endsupports a socket is for the bulb 15); The socket may be. securedin'place by molding, as indicated at 20, or otherwise. The mirror 21 isadjustablysecured to ahinge block :22 which in turn is pivotaily securedto the base 8: in this-instancel have pnovided ears 23, 2- between whichthe hinge block is located. In this instance, the mirror carries a brace24 hav ing an arcuate extension 25 having a slot 26 for the passage of alocking bolt 27. said bolt engaging the block 522. The upper end ofbrace 24 carries a projection or keeper 2R having an opening therein tobe engaged by,

a teat 29 carried by a latch 30 supported by the shell 9. The. radialpoint of the curved projection 25 will be located at about the point ofcontact of the upper surface of the keeper 29 and latch 30: hence saidmirror can be adjusted toward or away from the lamp when bolt 27 isloosened. without interfering with the engagement of thelatch and keeper29. As the axis of the bolt 27 is in alinement with the axis of the teat29, the mirror'can be adjusted in a vertical plane'without interferingwith the engagement of the latch and keeper. It will be apparent thatthe mirror is adjustable in a vertical plane as well as toward'or awayfrom the lamp. Tn this instance, the base 8 carries a threaded nipple 31to be engaged Patented Feb. 15, 1921. Application filed April 26, 1920.Serial no. 376.438.

to automatically close the circuit for the bulb 19 when the mirror ismoved out of alinement with the lamp, when said lamp is to be used (seedotted lines in Fig.- 1). To this end I provide a switch operable whenthe mirror is moved down; in' this instance when lowered all the way.down.

block 22. As herein embodied the switch consists of a block ofinsulating material 34 carried by the base 8 and contacts 35 and 36, thecontact 36 being movable and passing freely through the block. To placethe contact 36 incircuit with the bulb, I provide I As hereinillustrated the switch 15 operated by the hinge ductor having connectedthereto one end of a second Wire 35}. The wires 38 and 39 will beconnected to a source of e ectrical energy or battery 40 for vehicleshaving a two wire circuit. For a. one Wire or ground circuit (see dottedlines 41, Fig. 1), the Wire 39 will not be connected, as the base 8 willbe a part of the circuit. When the mirror is lowered the hinge block-22Will bridge the contacts 35 and 36 and the lamp will burn. Whether thecircuit is two Wire or ground,

the yieldability of the rod will lend Sui? ficient spring action to thecontact 36 to I maintain same in firm contact with the hinge block. Whennot in use the outer end of contact 36Will extend slightly beyond theouter end of contact 35. Instead of employ ing the contacts and 36,1inayuse a single movable contact 42 in Fig. 7, Which-passes through ametal tube 43 but insulated therefrom by a bushing 44. The metal tubewill have connected thereto one endof a circuit Wire 45. When contact 42is forced in, the head 46 will contact with tube 43 thereby completingthe circuit,fo1 the bulb. The contact 42 engagesthe rod 47 carried bythe socket 48, the same as contact. 36 engages rod 37. The oppositecircuit wire is indi cated by 49. The insulating block as may be held inplace by means of a screw 50 (see lt will also be apparent thatthemirror can be adjustedWithout affecting the hinge block; hence, theswitch and hinge block will always cooperate to close the circuitregardless of the'position of the mirror relative to the lamp, TheWeight of the mirror will maintain the hinge block in contact with theswitch contacts.

Havmg described my invention, What i claim is 1. A casing for electriclamps, consistine;

of a split shell member, an annular channel at each edge thereof toreleasahly engage a lens, a support, means to secure the shell at oneend to said support and means to slidably connect the other end of saidshellto said support.

2. A. signal device having a White front lens, a red rear lens, a mirrorinovably mounted adjacent the signal device and nor mally concealing thered lens, an electric lamp to illuminate the red and white lenses,

an open circuit therefor, and means associ ated with the mirror to closethe said circuit when the mirror 18 moved to expose the red lens.
